Measurement of the Ar(1sy) state densities by two OES methods in Ar-N2 discharges

Autor: Isola, Lucio Manuel, López, Maia Melina, Cruceño, Javier Marcelo, Gomez, Bernardo Jose Armando

In this work, results from two methods for the determination of the Ar(1sy) densities are compared in an Ar–N2 discharge. These methods involve measurements of optical emission spectroscopy (OES). The first method (band method) uses the bands belon

Relationship between grain size and thermal hysteresis of martensitic transformations in Cu-based shape memory alloys

Autor: Ph. Vermaut, L. Isola, Jorge Alberto Malarria, P. La Roca

The effect of grain size on thermal hysteresis is studied in ribbons and thin strips obtained by rapid solidification techniques. Results show a strong increase of the hysteresis width when the grain size is below ∼100μm. This effect is attributed
